Abstract
Palladium, platinum and rhodium complexes of rac- and meso-bis(1-diphenylphosphinoindenyl)iron(II) ( 1) are reported. Both rac and meso isomers of {bis(1-diphenylphosphinoindenyl)iron(II)}palladium dichloride ( rac- and meso- 2) were characterized by X-ray crystallography along with the rac isomer of the Pt analogue ( rac- 3). NMR analysis of the rhodium complex [{bis(1-diphenylphosphinoindenyl)iron(II)}(cyclooctadiene)rhodium(I)] tetraphenylborate suggests a similar structure in solution. Coupling reactions of n- and sec-BuCl with bromobenzene in THF are catalysed by rac- 2 and found to be similar to (PPh 3) 2PdCl 2 but poorer than (dppf)PdCl 2 in diethyl ether.
